Programming Languages Used For App Development

If you want to be a mobile app developer in 2021 but aren’t sure which programming language to use to get started, you’ve come to the right place.

App developers are in high demand as the demand for mobile apps grows every day. People with Android and iOS app development skills are in high demand, as both large and small businesses just hire an app development agency to build their mobile apps.

While there are many programming languages available, not all of them are suitable for app development. This is why it’s important to be aware of your options and select the best programming language that can not only help you create apps for Android and iOS but also help you become a more all-around app developer.

For aspiring app developers, there are many options for getting started with app development. In 2021, the following are the top five programming languages for app development:

1. JavaScript

JavaScript is the most popular web language. The popularity of frameworks such as jQuery, Angular, Vue, Svelte, and React.js has increased. Because you can’t get away from the internet, it’s best to learn JavaScript sooner rather than later.

Even if you are not using Angular JS or React JS, there are many other libraries based on JavaScript, such as jQuery, and it is also the most popular language for client-side validation, making it worthwhile to learn JavaScript.

2. Java

Java is yet another popular, powerful, and effective programming language that is in high demand for job and career advancement. While Java is primarily a server-side programming language used to build robust backend servers, it can also be used to create Android apps.

There are numerous advantages to learning Java for beginners who want to become app developers. You can not only create Android apps, but you can also become a full-stack developer by writing a backend in Java.

3. Swift

If you are interested in iOS development, such as creating apps for the iPhone and iPad, you should seriously consider learning Swift in 2021. It has supplanted Objective C as the preferred language for creating iOS apps. 

Swift is similar to Python, and it is also the official programming language for iOS, so learning Swift programming language is sufficient.

Advantages

  • Swift has a great IDE called Xcode that is self-contained and makes it easy to include libraries by using workspaces.
  • Swift is a type-safe language that is simple to read, understand, and code in, and it detects the majority of beginner errors at compile time.

Swift can be used for server-side programming. This is still a new concept that can be difficult to learn depending on where you work because most companies have their own framework or use one of the big ones.

4. Kotlin

If you are serious about developing Android apps, Kotlin is the programming language to learn in 2021. It is most likely the next big thing in the Android world. Kotlin has native support, and many IDEs, including IntelliJ IDEA and Android Studio, support Kotlin for Android development.

Advantages

  • The language is clear and concise, with modern features.
  • Allows you to use lambdas for functional programming.
  • Checked exceptions for typesafe
  • Excellent tooling and community support.

Kotlin is being marketed as next-generation Java, but it is not there yet. Compilation time is 2x to 3x slower than in Java (Incremental compilation is available for IDEA but not yet for Gradle)

The main advantage of learning Kotlin is that it is the official app development language for Android apps, and Google will continue to promote it.

5. Dart

Dart is a general-purpose, object-oriented, open-source programming language created by Google in 2011. Dart employs a ‘C’ syntax and can optionally transcompile it into JavaScript. It is used for client-side as well as server-side web development. Dart is also used in mobile development, both native and cross-platform.

Pros

  • When used to C-style syntax, this language is simple to learn.
  • Code can be shared between web and mobile applications.

Cons

  • To support the core domain, many subs and generic domain packages may need to be written. Backend (API/Server) focus is currently very low.

Before we conclude, it is preferred by mobile app developers in any top app development agency like InfiniSys – a leading app development agency to use JavaScript or Java as well as Dart. Because Swift and Kotlin are expensive deals and clients refrain from that. If you’re an app developer, then it is recommended you initially focus on learning the said three languages first.
